Price is the dependent variable and there are a number of independent variables including square feet, beds, baths, heat, garage, basement etc. that is used to explore and model the relationship between these variables. Central Tendency and Dispersion Here statistical tools are used to measure the central tendency and dispersion to make the data in the survey more meaningful and easier to understand. The Median Home Price: Here the aim is to determine the median price of the houses based on Price. In the housing market it’s important to know the median price of homes in a sample size. Using Minitab the following results were obtained. Descriptive Statistics: PRICE Variable N N* Mean SE Mean StDev Minimum Median Maximum PRICE 108 0 97.99 2.54 26.43 59.00 92.47 195.00 As per the Minitab computations above the median price for the list of 108 houses in our survey is $92,470. From the computation the cheapest house is priced at $59,000 whilst the most expensive house is $195,000. From the computation we also know that the average cost per house is $97,990. In the following computation two variables are used, Price and Fireplace. Variable FIRE N N* Mean SE Mean StDev Minimum Median Maximum PRICE 0 12 0 72.61 2.79 9.65 61.50 69.97 98.00 1 96 0 101.16 2.67 26.16 59.00 95.85 195.00 From the minitab results above we can tell that the average cost of a house without a fireplace is $72,610 and is $28,550 cheaper than a house with fireplace. This information can be useful in determining the value of a house an owner intends to sell. Another important feature that
